We have two kids ages 7 and 9 and got an 8 week old puppy about 2 months ago. It is a LOT of chaos and work, but also really fun and we love our puppy. There have been unexpected benefits (significant reduction in screen time because the kids just want to play with the puppy, and increase in exercise for all of us on walks). Crate training has been going well. She only woke up during the night the first two nights we had her, and we take her out about every 3-4 hours, usually she gets 3 walks a day for 20 minutes or so. We've had only a handful of pee accidents in the house. One poop. We both work full time, but work at home on alternate schedules so we've managed it with a dog walker one day a week and do her mid-day walk around noon. We are going to get a dog walker more days per week because the mid-day walk has been really hard to manage because our work days are unpredictable in terms of being able to take a lunch break stress free. The hardest thing is probably around dinner time, when kids are tired and fighting, parents are tired and trying to get dinner made, the puppy is barking or chewing on the rug or running away with a toy or object she can't chew on. The one thing that was completely unexpected is the vet and the bills associated with that. We expected the initial well visit and vaccines, but she also had round worm (vomiting) and then as soon as she recovered from round worm she got another parasite that had her vomiting again and had to be treated. We've spent much more money than we expected. It is sort of like having a new baby, although it is getting easier MUCH quicker.
